Since the failed exterior project and the board’s heat pump decision, sale prices at 3920 have dropped
The most common unit at 3920 Mystic Valley Parkway, a 1,206-square-foot two-bedroom, two-bath, has been selling for less in 2026 than it did in 2024. Over the same period, the citywide Medford condo median barely moved.
Based on public listing data we could find; not an appraisal. Sample sizes are small, and individual units differ in floor, view, and condition.
The numbers
We counted only sales whose price and date we could confirm on a public listing page, and left out the penthouse. That leaves four 1,206 sf sales in 2024 and five in 2026. We found no 1,206 sf sales in 2025.
- 2024 (4 sales): #616, March 15, $600,000; #522, March 8, $610,000; #916, March 25, $635,000; #1009, October 9, $640,000. Median $622,500 (about $516/sf).
- 2026 (5 sales): #514, October 15, $555,000; #423, June 29, $560,000; #620, March 17, $588,000; #816, August 6, $615,000; #704, June 11, $629,000. Median $588,000 (about $488/sf).
That is a drop of about 5.5% in the median. Two of the three sales since June, at $560,000 and $555,000, came in below every 2024 sale of the same size we could confirm. (A reported May 2024 sale of #1120 at about $705,000 appears only in a search snippet we could not verify, so we left it out. Including it would raise the 2024 median to $635,000.)
Vertical scale starts at $560,000 so the change is visible. 2024: 4 sales; 2026: 5 sales through October 15. Over the same period the Medford citywide condo median went from $685,000 to $686,750. Source: public listing pages listed below.
Blue: Medford citywide condo median ($685,000 in 2024, $655,000 in 2025, $686,750 in 2026 through Sept. 30; tamelaroche.com). Red dashed: 3920 median for the standard 1,206 sq ft unit ($622,500 in 2024, $588,000 in 2026 through Oct. 15); we found no 1,206 sq ft sales at 3920 in 2025, so its line connects 2024 directly to 2026.
Medford overall
Citywide, the Medford condo median was $685,000 in 2024, $655,000 in 2025, and $686,750 in 2026 through September 30, according to tamelaroche.com. That is roughly flat over two years, while 3920’s standard unit lost ground.
A one-bedroom example
Unit #217, an 826 sf one-bedroom, sold for $449,000 in December 2021 and again for $419,000 in February 2026, about 7% less, more than four years later.
If you are buying or selling at 3920, look at the building’s own recent sales, not just citywide figures.
